#153064 - Accessor functions? Responding to: ???'s previous message |

If you use accessor functions then you can swap a SPI eeprom with a I2C eeprom, or even an internal EEPROM very easily. "Accessor functions" are new to me. A quick search leads me to believe that they are only a C++ feature? Can someone elaborate how these work and how they apply here? I should read your boss's code very carefully before you make radical changes. Note that the larger size serial eeproms have a 2 byte address register. Oh, I have! It's all in assembly, without comments of course. The new EEPROM has the additional address bit(s) mapped over the hardwired pins. So instead of having A2, A1 & A0 pins setting part of the address, you lose A0 pins' functionality for the 512 byte part (losing A0 & A1 for the 1024 byte part). tom |
